What is a Lightboard?

A Lightboard is a glass chalkboard pumped full of light. It’s for recording video lectures. You face towards your viewers and your writing glows in front of you!

The Lightboard lets you draw highly visible sketches and equations as you lecture, facing the camera, and capturing good quality video.

How we made it

Lightboards are a teaching tool particularly helpful for flipped or hybrid classes where the professor desires to record lecturettes and write without having to lose eye contact with viewers, or do tedious post-production.

Two tricks are necessary to make the effect work. First, the transparent glass panel, placed between the presenter and the camera, is edge-filled with LED lights. Neon dry erase markers catch that light and the writing glows. A second trick reverses the image, so the viewer sees what the professor sees.
